| 摘 要： | 通过对不同粉油比的沥青混合料进行高温车辙试验、旋转试验机试验,对不同粉油比的沥青胶浆进行动态剪切试验,利用扫描电镜观察沥青胶浆的微观界面,研究了粉油比对混合料高温稳定性的影响。试验结果表明:粉油比越大,抗车辙能力越强,而且粉油比是通过影响沥青胶浆的抗剪切强度来影响沥青混合料高温稳定性,并提出了最佳粉油比范围在0.8~1.2之间。

| Abstract: | The paper presented rutting test and gyratory testing machine test on asphalt mixture of different filler to bituminous ratio,with dynamic shear rheometer and SEM used to analyze the microstructure of asphalt mortar of different filler to bituminous ratio,and studied the effect of filler to bituminous ratio on stability of asphalt mixture at high temprature.The test results indicate that the higher the ratio of filler to bituminous,the better is the ability of rutting resistance,and the ratio influences the stability of asphalt mixes at hightemperature through the effect on the strength of shearresisting,and that the range of optimal ratio should be between 0.8 and 1.2. |
